Title: Head sink and composite semiconductor device using it
Inventor: FUKUDA EIGO
IPC: H01L23/36
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To reduce the final amount of warp in heat sinks, cracking in insulating substrates and variation in characteristics of pellets, by forming a hardened part on the top of a heat sink by press. SOLUTION: The surface of a heat sink 12 with a soldered insulating substrate is wrought into a recessed shape to form a hardened part. The heat sink 12 with the hardened part formed thereon is formed into a projected shape so that the amount of warp at its central portion 12a is S10. When the insulating substrate 3 is soldered, the central portion 12a turns into a recessed shape with an amount of warp of S20. When the workpiece has been left for several days, the amount of warp in the central portion 12a is as slight an amount as S30, and the shape of the workpiece is stable. An insulating case is brought into contact with the periphery of the heat sink 12, a lid with external terminals led out is placed on the open end, and the inside of the insulating case is filled with resin.  Thereby warp in, and the amount of variation after leaving of, the heat sink 12 can be reduced, and cracking in the insulating substrate 3 soldered to the heat sink 12 can be reduced; therefore, adverse effect on the characteristics of a composite semiconductor device can be prevented.

Title: Magnetic recording medium
Inventor: SOMEZAWA MASASHI
IPC: G11B5/702
Filed: 1988-03-30
Abstract: PURPOSE:To prevent the elimination of a binder from magnetic powder so that the magnetic powder is improved in dispersibility and is decreased in dislodgement and the electromagnetic conversion characteristics and the durability of a magnetic coated film are improved by using a polyurethane resin having a residual aminocarboxylic acid group in the molecule as the binder of the magnetic layer. CONSTITUTION:The polyurethane resin having the residual aminocarboxylic acid group in the molecule is used as the binder of the magnetic layer 2 which is provided on a nonmagnetic base 1 and consists essentially of the magnetic powder and binder. The residual aminocarboxylic acid group bonds securely to the magnetic powder by multidentate coordination on the surface of the magnetic powder and improves the dispersibility of the magnetic powder having all surface characteristics (neutral, acidic, basic) and the boundary face intensifying property of the magnetic coated film. Since the surface of the magnetic powder having the neutral and acidic surface characteristics and the residual aminocarboxylic acid group are securely adsorbed, the adsorption of various additives such as fatty acid having proton- donating atomic groups to the magnetic powder is prevented. The elimination of the binder from the magnetic powder is thereby prevented and the magnetic powder is improved in the dispersibility and decreased in the dislodgment. In addition, the electromagnetic conversion characteristics and durability are improved.
